byte_search_publishersSearch PayPerByte publishers by topic and sort order. Returns publisher addresses, topics, subscriber counts, message counts, and price-per-KB.byte_get_publisherGet 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_statsGet PayPerByte network-wide statistics: total publishers, messages streamed, and total subscriber fees settled in USDC.byte_check_subscriptionCheck if an address is subscribed to a specific publisher on PayPerByte.byte_get_token_balancesGet 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 that byte_buy_data spends.byte_list_feedsList all active data feeds in the PayPerByte catalog with topics, price-per-call, and frequency (pricePerKB is a deprecated alias).byte_list_my_subscriptionsList 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 timestamp of the last message received. Use this to see what you're currently paying for and decide whether to unsubscribe.byte_subscription_healthGet 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), 'moderate' (20-50% cadence shift or 24-48h silence), 'significant' (>50% shift or >48h silence), or 'unknown' (new publisher, insufficient baseline). Use this to detect when a publisher you subscribe to has pivoted content or gone dormant.byte_unsubscribeUnsubscribe 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 content (check with byte_subscription_health first) or when you simply don't want the feed anymore. Requires PRIVATE_KEY for the connected wallet.byte_subscribeSubscribe 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 (the contract's allowance-skip path emits DataStreamed with amount=0 on transferFrom failure rather than reverting). Pass skipAllowance: true to opt out and set a finite cap manually. Requires PRIVATE_KEY.byte_register_publisherRegister 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 USDC stake is approved to DataRegistry first if you choose to post one.byte_publish_dataPublish 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.- +3 more on the listing page

fetchHTTP fetch with automatic authentication and payment handling. Makes the request, retries with SIGN-IN-WITH-X when the route exposes a SIWX challenge, and only pays if the route still returns 402. Returns response data and the final response headers, including raw payment receipt proof when supplied by the server, along with payment details (price, tx hash) if a payment was made. For endpoints you haven't called before in this session, you MUST call check_endpoint_schema first to confirm the request body schema. Skipping this causes 400 errors from wrong field names.get_balanceGet your total USDC balance across all supported networks. Auto-creates the wallet on first use (~/.agentcash/wallet.json). Use this before paid API calls to confirm you have funds available.list_accountsList wallet accounts for each supported network. Returns the network, address, balance, and deposit link for every supported network so you can see where to fund the wallet. Auto-creates the wallet on first use (~/.agentcash/wallet.json). If onboardingCta is present, show its message to the user — it means they haven't onboarded yet and need to either visit the onboard link or deposit directly.check_endpoint_schemaGet the input/output schema and auth mode (paid or SIWX) for a single endpoint. Call this to see exactly what fields the request body expects and what the response contains. Returns the schema from the origin's OpenAPI spec. Optionally pass sample_input_body to probe the endpoint live (without payment) for an exact price quote — do this when pricing is dynamic (range-based or variable), or when you're unsure about the input schema. Treat auth mode as advisory: fetch handles both SIWX and paid routes.redeem_inviteRedeem an invite code for free USDC on Base. One-time use per code. Returns amount received and transaction hash. Use get_balance after to verify funds, or list_accounts if you need the per-network deposit links as well.discover_api_endpointsList available endpoints at an API origin. Returns endpoint URLs with descriptions of what each does and the auth mode for each (paid or SIWX). Works with any origin, not just the registered ones. Call this when you need to see what routes are available at an origin — whether it's one of the registered origins or any other origin you've identified as useful. Treat the auth mode as guidance for what the route may require; fetch handles both SIWX and payment. The response always indicates whether guidance is available. Guidance is documentation published by the API provider explaining how endpoints work together, edge cases, and usage tips. compact guidance is included automatically; set include_guidance=true to force-include full usage documentation when you need to compose two or more endpoints or need clarification on how the origin works.report_errorEMERGENCY ONLY. Report critical MCP tool bugs. Do NOT use for normal errors (balance, network, 4xx) — those are recoverable.update_settingsUpdate user settings (persisted to ~/.agentcash/settings.json). Currently supports maxAmount — the maximum USD amount allowed per fetch request. If a fetch response requests more than this, the payment is rejected. Returns the current settings after applying changes.get_settingsGet current user settings. Returns persisted values from ~/.agentcash/settings.json with defaults applied.bridgeBridge USDC between supported networks using the current wallet. Requires a source network, destination network, and amount. Use this when funds are on one supported network and the user needs them moved to another. Bridging is subject to fees.searchSearch for relevant paid API services by describing what you need in natural language. Returns the best matching origins with endpoint details and pricing. The top result includes the full input/output schema so you can call it immediately via fetch. Only use this when you DON'T already know which registered origin to use. If the task clearly maps to a registered origin (e.g. people search → StableEnrich, image generation → StableStudio), skip search and go straight to discover_api_endpoints on that origin. Search is for discovering NEW or UNKNOWN capabilities outside the registered origins. Set broad=true to widen the search to include newer, unvetted tools that may not have established trust. Use this if the default results don't cover what you need.sessions_closeClose an MPP `tempo:session` payment channel. Pass the channelId surfaced in a prior fetch's paymentInfo together with the same URL you originally fetched. Signs a close credential with the on-chain settled cumulative amount and POSTs it to the server, returning the on-chain settlement transaction hash when available. Use this when you want to finalize a channel rather than leaving it open for the server to settle on its own schedule.
