byte_search_publishers

Search PayPerByte publishers by topic and sort order. Returns publisher addresses, topics, subscriber counts, message counts, and price-per-KB.

byte_get_publisher

Get on-chain info for a specific PayPerByte publisher: status, subscriber and message counts, USDC revenue, and the registered schema (size bounds, cadence, price-per-KB).

byte_get_network_stats

Get PayPerByte network-wide statistics: total publishers, messages streamed, and total subscriber fees settled in USDC.

byte_check_subscription

Check if an address is subscribed to a specific publisher on PayPerByte.

byte_get_token_balances

Get USDC and ETH balances for an address on Arbitrum Sepolia (the on-chain testnet layer — MockUSDC settles subscriptions and fact-oracle queries there). Does NOT show the Base-mainnet USDC balance th…

byte_list_feeds

List all active data feeds in the PayPerByte catalog with topics, price-per-call, and frequency (pricePerKB is a deprecated alias).

byte_list_my_subscriptions

List every active subscription for a given wallet address. Each entry has the publisher address, topic, status, when you subscribed, messages received in 7/30 days, USDC spent in 7/30 days, and the ti…

byte_subscription_health

Get the content-drift signal for a publisher. Compares their last 7 days of publishing activity (cadence, message count) against their 23-day baseline (days 8-30). Returns 'stable' (steady publishing)…

byte_unsubscribe

Unsubscribe from a publisher's data feed. Takes effect next block: no more billing, no more data flow. Reversible — you can resubscribe later via byte_subscribe. Use this when a publisher has pivoted …

byte_subscribe

Subscribe to a PayPerByte publisher's data feed. By default also sets USDC allowance to DataStreamLib to type(uint256).max so the subscription doesn't silently lose payments when allowance depletes (t…

byte_register_publisher

Register as a data publisher on PayPerByte. Registers a schema and the publisher on-chain. Requires PRIVATE_KEY. PayPerByte v1 publishers are first-party and unstaked — leave stake at '0'; a non-zero …

byte_publish_data

Publish data to a subscriber via the PayPerByte DataStream contract. Hashes the payload, records size on-chain, and settles the fee in USDC. Requires PRIVATE_KEY.

byte_query_fact

Query a PayPerByte fact-oracle publisher for a signed answer with citations. Posts the question to a registered fact-oracle publisher (topic='fact-oracle'), waits for the on-chain BroadcastStreamed re…

byte_buy_data

Buy a single data packet from any PayPerByte feed via the x402 payment gateway. No subscription, no allowance, no prior on-chain setup — pay-per-call USDC settlement. The MCP server signs an EIP-3009 …

byte_verify_payload

Verify-before-act: confirm a data payload an agent is about to act on actually matches what the publisher cryptographically attested to on-chain. Recomputes keccak256 of the received bytes and compare…
