ONE read that tells you, for a chain and for the lane you reached Robyn on, exactly what stays private (relay lane, PQ transport, private mempool / sequencer) and what is still public (on-chain settle…
Hands a relayer-signed settlement receipt (from robyn_settle / a completed route) to the counterparty's sealed messaging-v2 mailbox, so they get verifiable proof (terms honored, authorized, clean prov…
Checks digest + relayer signature + signed terms of a receipt you received (e.g. opened from your v2 mailbox). Read-only.
List the Robyn gasless chains and the cross-chain route graph (22 EVM nodes + Stellar), plus the relayer/Permit2 addresses. No credentials needed.
Best gasless route to move a token from one Robyn chain to another. Returns estimated output, the bridge used, duration, and the Robyn fee. Read-only — moves nothing. IMPORTANT: check `quoteOnly` on t…
The one-verb primitive. Say where value should go; Robyn returns the best route (all rails compared), the gasless method (no native token needed), the privacy posture that will apply (API-relay + priv…
Returns a relayer-SIGNED attestation that, as of a signed timestamp, every component was up (router, signing daemons, MCP, privacy relay) AND the privacy invariants held — the adversary probes could n…
Run this before robyn_prepare/robyn_submit. Returns decision GO or NO_GO plus typed `blockers` (each with a `fix`) and `warnings`. It catches, for free, the failures that otherwise cost gas: a fixed c…
Check whether an address holds a recognised member NFT and what it gets. Members pay ZERO on cross-chain transfers of $0.10-$25 to low-cost chains, 15bps instead of 25bps routing, and 10% instead of 2…
Status of an in-flight route by id (BRIDGING → DONE), with the destination tx once delivered.
Plan a gasless cross-chain move and get the exact payload to sign. This hosted server never holds your key: call this, sign what it returns with your own wallet, then call robyn_submit to have the rel…
Turn a plain-language or structured intent into a concrete plan plus the EXACT payload to sign. Costs nothing, moves nothing, needs no key. Returns status:"sign" with signRequest, or status:"quoted" i…
Runs the identical path end to end against the sandbox: no key, no funds, no broadcast. Use this to prove an integration works before touching real money.
Relay an intent you already signed. The relayer broadcasts it and fronts all network gas; your account needs no native token. Build `permit2` from robyn_prepare: sign its signRequest.eip712 payload (c…
Explains the opt-in netting ledger: transfers between two ENROLLED accounts settle as a book entry — no chain, no gas, no fee, instant, at ANY size including amounts below every per-chain cost floor. …
Whether an address is enrolled (and therefore custodied), its internal balance, recent history, and `nextNonce` — which you MUST use when signing the next transfer or withdrawal. An address that never…
Free and read-only. Given an amount, ranks EVERY exit chain by what actually arrives after the destination payout cost is deducted. Those costs differ by more than 1000x (Avalanche delivers ~$0.99994 …
Internal transfers produce NO transaction hash because no transaction occurs — this append-only journal is their only record. Never truncated; page with `before` (a seq number). Use this when a user a…
Publishes what Robyn OWES across all netting accounts against the real relayer float backing it, per chain. Solvency is checkable rather than asserted. Deposits are refused if they would push liabilit…
Returns the EXACT message the account must sign with its OWN key to open a custodial balance. This endpoint holds no key and enrols nobody — it returns the text; the user signs it, then POST {address,…
Returns the exact string to sign, with the correct next nonce, for a free instant transfer between two ENROLLED accounts. Signs nothing and moves nothing — the sender signs the returned message, then …
Your OWN payment history with a recipient address: how many times, how recently, and whether this amount is typical. Call it before paying an address you have not confirmed. THIS IS NOT A REPUTATION S…
ONE call combining serviceability, routing competitiveness, cheaper alternatives, delivery basis and mandate budget into a single go/no-go. Call this before executing rather than making five separate …
Post the request you INTEND to make and get back what is missing or unsafe, with the concrete consequence. Run this before your first live execute. Findings marked `unsafe` can lose money or make you …
Ordered playbooks for real goals: pay-someone-safely, prove-what-i-spent, spend-within-a-budget, handle-failures-well, stay-current. CALL THIS BEFORE IMPROVISING A SEQUENCE. Each step says what it ans…
Machine-readable API history. Pass the version your integration was built against as `since` and you get only what has changed after it, with an explicit `breaking` flag on each entry. CHECK `mustAct`…
The full error taxonomy: every errorCode, whether it is retryable, and the suggested recovery action. Read this once and branch on errorCode instead of parsing messages.
Check what ACTUALLY happened to a settled transfer, against the destination chain rather than Robyn's own database. Optionally assert who should have been paid (`recipient`) and the minimum that shoul…
Validate a WHOLE multi-step workflow up front instead of one hop at a time. Fees and durations accumulate across steps. Evaluation stops at the first unroutable step rather than reporting speculative …
A statement of every transfer in a window with each fee broken down, SIGNED by Robyn's relayer key (EIP-191). Use this when you must PROVE to a principal what you spent — your own summary is a claim b…
Reconstruct a settled transfer unit by unit: destination payout gas, Robyn margin, or a Robyn SUBSIDY where Robyn absorbed a loss. Each line names who was paid and how the figure was derived. Anything…
How long settlements ACTUALLY take, per rail and per corridor — not a single advertised constant. CHECK `basis`/`status`: below the sample threshold this returns `insufficient-data` and the figure is …
Poll for spend, nearly-exhausted, exhausted, approval-required and revoked events on a principal's mandates. Pass the returned `cursor` back as `since` for only what is new. Use this to tell a princip…
List all mandates granted by a principal address, with remaining budget, co-sign threshold, expiry and revocation state. Use this before telling a user they are safe: live mandates can still be drawn …
For mandates with a co-sign threshold, check whether a specific spend needs the principal to approve it and get the exact digest they must sign. The digest binds the mandate, the transfer AND the amou…
A signed certificate listing every spend counted against a mandate, the budget, the total spent, and whether it stayed inside. Hand it to the principal at the end of a period. Every spend listed was V…
Check a proposed spend against a signed spending mandate BEFORE making it. Returns WITHIN_MANDATE, EXCEEDS_MANDATE or EXPIRED plus the remaining budget. If EXCEEDS_MANDATE, do NOT split the spend into…
Remaining and consumed budget for a signed mandate. Consumption counts ONLY transfers verified on-chain, so the figure cannot be inflated by claiming spends that did not happen.
Turns a price into a decision. Returns concrete, QUANTIFIED changes — a cheaper destination chain with the exact saving, the size at which a fixed payout cost stops dominating, whether the instant flo…
Returns the full routing decision: every rail that quoted, what each would deliver, the margin the winner won by, and which rails stayed SILENT and why. Signed, so you can archive the rationale. CHECK…
A signed, timestamped record of current capability: which chains can actually be PAID OUT ON right now, which are merely policy-eligible, which rails are execute-ready, and whether delivery figures ar…
Assembles EVERYTHING about a settled transfer in one call: the on-chain verification, the unit-by-unit fee breakdown, what the alternative route would have cost, and whether the delivery time is measu…
Build a canonical payment request (payee, chain, token, amount, memo, expiry) and return the digest for THE PAYEE to sign with their own wallet. Robyn does not sign these and holds no payee keys — a r…
ALWAYS run this before paying a request you received. It confirms the payee address, chain, token and amount were signed by whoever controls the payee address, and that the request has not expired. If…
After paying, prove it: re-checks the transfer against the DESTINATION CHAIN and confirms the payee was paid at least the amount requested. Returns paid=true only on a verified on-chain result; paid=n…
Check a signed refusal receipt. Send header `x-anygas-receipt: 1` on any request and, IF Robyn refuses it, the error response carries a signed `refusalReceipt` recording what was asked, when, and why.…
The canonical Robyn EIP-7702 batch-executor delegate: its address on each of the 22 EVM chains, the ABI, and the EIP-712 scheme for executeSigned. Delegate to this and the relayer can sponsor your tra…
Check that a signed EIP-7702 authorization tuple recovers the expected account, and whether its nonce matches the live account nonce. Free, read-only, moves nothing.
Price or request an EIP-7702 sponsored transaction: Robyn submits your signed authorization as a type-4 transaction and PAYS THE GAS, so your account needs no native token. Over this HOSTED endpoint t…
An agent's own Aave v3 / Moonwell position (aUSDC/mUSDC) per chain + the capped allowance it granted the relayer + live APY (best-yield auto-selected). Non-custodial: funds stay in the agent's wallet,…
Read-only JIT quote: how a spend would be fulfilled from an agent's Aave yield venue (draw <= your allowance -> Aave/Moonwell withdraw -> gasless deliver). Moves nothing.
Spend from your yield (Aave v3 or Moonwell) with ONE EIP-712 signature: Robyn pulls only up to your on-chain aUSDC/mUSDC allowance, unwinds exactly what is needed, and delivers gaslessly; the remainde…
Sonar — PRIVATE · SEALED · POST-QUANTUM MESSENGER (broadcast to everyone, understood by one, remembered by none). Hybrid ML-KEM-768+X25519 encryption, a one-time stealth handle per message, fixed-size…
Every published v2 mailbox. PUBLIC rows carry {address, metaAddress, kemPub}; PRIVATE rows (the default since 2026-08-28) carry {handle, metaAddress, kemPub} and deliberately NO address. Identical for…
For a Robyn name or NULL handle the server must resolve it, so this reveals your intended recipient to the server — prefer robyn_message_directory when you have an address. Returns {address|handle, me…
Relays a message you sealed locally with /svc/msg2-sdk.mjs (seal(mailbox, inner) → {ephemeralPubKey, viewTag, ct}). This tool cannot encrypt for you: sending plaintext here would expose it to the rela…
Returns released rows {id, ephemeralPubKey, viewTag, ct, releaseAt, nextAfter}, identical for every reader. Scan locally with the SDK (inbox(identity)) — checkStealthAddress with your viewPriv, then o…
Registers a mailbox so others can seal to you. PRIVATE BY DEFAULT: the server stores only a salted hash of your signing address — pass `handle` to be reachable by name (agents get the same handle clai…
Plus sells capacity (rate-limit-exempt sends), funded cover rows and signed/anchored Merkle proofs — never a "more private lane" (that would be a smaller crowd). Paid in ETH (Robinhood Chain, Ethereum…
Creates an invoice for one bundle (500 passes, $3 quoted in the chosen asset). Returns {invoiceId, payTo, amount (base units), human, chainId, expires}. Pay from any wallet; then blind tokens locally …
Status, remaining passes and payment details for an invoice. Read-only.
Try Plus before paying: submit up to 20 BLINDED tokens (base64, from plus-sdk blindTokens()) and receive blind signatures — identical unlinkable passes to paid ones. One trial per day per caller. Unbl…
Submit BLINDED tokens (base64, from plus-sdk blindTokens()) with the payment txHash. Payment is verified on-chain (recipient, amount, confirmation; one tx pays one invoice), then each blinded token is…
Merkle inclusion proof for an anchored row id: leaf, path, root, the signer’s EIP-191 signature over the batch statement and the on-chain tx when enabled. Verify locally with plus-sdk verifyAnchorProo…
The last purge statement (expired count, cumulative, root of purged ids) signed by the operator. Read-only.
The live NULL manifest: every product (messenger, Pay, Vault, Drop, Legacy, Agent Wire, forward secrecy), its status, its page, the wired/proposed integrations between them, the security spine, and th…
Fetches {spk, sigSpk, otk, otksLeft} for a recipient so you can start an X3DH-PQ forward-secret session (SDK: fs.startOutbound). ALWAYS fetch by META-ADDRESS: the sigSpk check verifies against the met…
Makes you reachable with forward secrecy: publishes your signed prekey bundle (medium-term spk + one-time otks) so peers can start X3DH-PQ sessions TO you. Generate and sign locally with the SDK (fs.g…
Reads an address balance through the NULL server-side RPC proxy, so YOUR IP never reaches any public RPC provider (this host queries upstream from its own address). BE HONEST ABOUT THE TRADE: querying…
One read that teaches an agent to use every NULL capability with the right privacy posture: create an identity, seal + send + scan, start forward-secret sessions, drop an anonymous tip, check a Legacy…
