POST https://angel.oroboros-design.com/agenten/signal/historical-gate · 1 observation
Backtest of the TradeSignal gate for one Binance spot pair before relying on it: the unchanged engine replayed on up to 30 days of closed 1h candles with 4h trend, every signal followed to stop, take-profit or 48 hours, returning win rates, average R and the split between gate=true and gate=false.

POST https://angel.oroboros-design.com/agenten/signal/input-guard · 1 observation
Prompt-injection and hidden-instruction scan for untrusted input before an agent acts on it: web pages, emails, RAG chunks, tool and MCP responses. Flags text aimed at the model (role override, fake system or tool messages, requests for keys, system prompt, history or payments, exfiltration links), invisible Unicode (tag smuggling decoded, zero-width, bidi), homoglyphs, base64 payloads and HTML hidden from humans, in 17 languages. Verdict clean, caution or hostile, score, findings, cleaned text.

POST https://angel.oroboros-design.com/agenten/signal/preflight · 1 observation
Pre-payment check for any x402 endpoint before an agent signs: one unpaid GET or POST {} reads the 402 (v1 body or v2 PAYMENT-REQUIRED header) and verifies network, official USDC contract, payTo, EIP-712 domain name and version, price traps (>= $1 caution, >= $1,000 do_not_pay), a max price, the host named in the requirement, latency and discovery files. Verdict pay, caution, do_not_pay or not_x402 with reasons and fixes. Never pays or signs.

POST https://angel.oroboros-design.com/agenten/signal/reconciliation · 1 observation
Payment-received check for USDC on Base: matches a list of expected amounts (optionally sender and reference) against the incoming USDC transfers of an address and returns each match with tx hash and time, the expected payments still missing and transfers that arrived unexpected. Answers whether an invoice or agent payment arrived without a block explorer.

POST https://angel.oroboros-design.com/agenten/signal/token-risk · 1 observation
Honeypot and rug-pull check for an ERC-20 on Base or Ethereum before a swap, approval or signature, read straight from the contract: upgradeable proxy (EIP-1967, beacon, clone), owner powers in the bytecode (mint, pause, blacklist, fee or max-tx setters, trading switch, burn from any address), owner renounced or active and the owner's share of supply; known issuers labeled. Risk low, medium or high with reasons. Signals, not investment advice.

POST https://angel.oroboros-design.com/agenten/signal/validate · 1 observation
Pre-trade sanity check before an order is placed: a crypto setup's entry, stop and targets scored against the live Binance spot market (stop distance vs 1h ATR, reward-to-risk, EMA20/50 trend on 1h and 4h, RSI14, distance from the current price), returning valid, weak or invalid with a 0-100 score, every check and the engine's own setup for the pair.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
