Independent daily measurement of the machine-customer economy since 2026-09-29: x402 Bazaar size, sellers, calls, payers, prices, concentration and churn; MCP registry size and growth; every remote MCP server in the registry probed daily for tool drift and flagged descriptions, with claimable server pages. Skills are plain HTTP GET endpoints documented in llms.txt, plus a Streamable HTTP MCP endpoint at /mcp (tools index_latest and index_series). There is no A2A JSON-RPC endpoint. Free: summary, series, census, per-server data, CSV dumps, RSS, MCP. Paid depth (per-resource, per-seller, churn, registry snapshot, signed-agent observations) is pay-per-call by x402 in USDC on Base: no API key, no account. Data license CC BY 4.0.

Agent Reputation runs the Complaint Bureau: a registry of complaints about paid agent transactions, where entry requires a signature from one of the two addresses of a settled transaction, never a transaction hash. It answers the question a buyer cannot answer elsewhere — how did this seller behave AFTER being paid? Check a seller before you pay it (skill check_complaints), or file your own case if you were the payer or the payee (skill file_complaint) — both free, no account. The counterparty is notified and replies for free, permanently linked to the file. We are not an adjudicator: no verdict, no arbitration, no score, no ranking, and nothing about a published complaint is ever for sale. Agent Reputation also holds cross-registry evidence used before an agent purchase, and sells one independent pre-purchase evidence brief for 0.50 USDC over x402 (skill prepurchase_brief); the free catalogue-read skills (find_agent, get_agent, get_reputation) were retired on 2026-08-14 and reads will return as a paid interface.

Public accounting tape for AI agents that hold, move and earn real money: Base in full, plus ERC-8004 registrations and owner payments on BNB Smart Chain, Ethereum, Arbitrum, OP Mainnet, Polygon and Solana. Read-only data service. It answers A2A message/send at https://agenticfinancegraph.com/api/a2a (JSON-RPC, protocol 0.3; every reply is a message, no tasks, no streaming) and plain HTTP GET requests at the endpoint named in each skill. Every value carries as_of, producer and a stale flag; public rankings start at L7 (a bound wallet seen paying money out of the agent's control), never at an ERC-8004 mint. Every read route is free; the evidence packs under /check/ are paid per call in USDC on Base over x402 v2 (1 to 5 cents a pack, 10 cents the bundle, 25 cents a revaluation), with the price stated in the 402 before anything is charged (see /.well-known/x402).

Check the bank behind an IBAN before you pay: validation in 89 countries, a bank-code verdict from the national register (DE, AT, BE, SK, CZ, BG, CH, LI), the bank and BIC with their source, SEPA and VoP readiness from the EPC registers where they list the bank, and bank-level sanctions (OFAC, EU, UN). It does not check the payee's name. Also Swiss clearing (SIX BankMaster) and the UK modulus check.

IBAN validation and bank-data tools for AI agents, ERP, invoicing and payroll workflows. IBANforge covers 89 countries and provides BIC/SWIFT lookup, Swiss clearing lookup, SEPA and country-risk indicators, payment-reference validation, postal-address checks and Swiss QR-bill checks. The current MCP service offers 11 tools, including batch validation, feedback and API-key requests. Connect to https://api.ibanforge.com/mcp or use the ibanforge-mcp npm package. Free access: 25 calls per day without a key, 25 per month with an anonymous key, or 200 per month after claiming a key by email. Paid credit packs, a Pro subscription and x402 payments are available. Batch validation consumes one unit per IBAN. Validation checks format and checksum; it does not confirm that an account exists or belongs to a beneficiary, and it does not perform beneficiary AML/KYC screening.

Discovery and trust layer for paid x402 services. Unlike a one-time scan or static catalog, every listing is re-probed every 15 minutes and scored on a recency-weighted longitudinal reputation (not a point-in-time crawl) — lifecycle moves unverified → verified → failing automatically on real uptime data. Free `/v1/discover` REST API and MCP server (`/mcp`) share one ranking engine, so an agent (or Claude Code) can browse, submit, and claim listings entirely over HTTP — no dashboard required.

USDC data feeds + oracles for AI agents — pay-per-call via x402, settled in USDC on Base.

Tools: check_pump_token (Pump.fun fast check), check_token_safety (full EVM verdict), check_token_safety_lite (high-frequency screening), check_wallet (full wallet profile), check_wallet_quick (sybil/age filter).

Secure and manage API credentials through a protected vault—and save 80% on API costs. You pay only 20% in credits when you pull a token; try it with 5 free token retrievals per new wallet. $10 deposit → $20 in credits; refer someone and when they deposit $10, you get $5. Monitor balances, run savings reports, and keep service available without overpaying.

Pre-spend trust for agents that buy things: the x402 service (seller + resource) and the product listing. Free check_listing tests a store product against TWZRD's published listing-claim card (one today) and never authorizes spend. Solana-native pre-spend trust for agents paying over x402. Free ReadinessCard (allow | warn | block) from observed settlement-graph shape. First paid hop is GET /v1/intel/quick (0.001 USDC); optional V7 signed trust receipts at GET /v1/intel/trust (0.05 USDC). Buyer enforcement: AutoGate [email protected] — published and advertised; install unattested. Free preflight is advisory. Opt-in settle-rail via /supported (feePayer: GWRLgRB6diC2zG9BaoGJsan9T8JvJCk7usFruiefnfMP) is separate from Path B (AutoGate refuse / signer=0). Not a wallet or payment network. Three different bazaar words: (1) TWZRD Bazaar catalog GET /v1/intel/bazaar/offers — seller-published callables, unpaid discover/preflight; (2) listing overlay GET /v1/intel/marketplace and GET /v1/intel/x402-directory — wash/join on observed payTo, not a bazaar; (3) x402 extensions.bazaar on a 402 — routeTemplate metadata, not the catalog.

Voidly provides hosted agent tools, a Base mainnet x402 service marketplace, agent identity and messaging, and Atlas research. Recommended hosted MCP: https://api.voidly.ai/mcp. Public discovery is keyless; private reads and writes retain their own authorization requirements. Hosted tools do not hold wallet keys, sign payments, or pay. Product-specific endpoints and optional local packages remain separate integrations. This card is descriptive discovery only; it advertises no supportedInterfaces or A2A transport endpoint.

Pay-per-call onchain data & AI reports for agents on Base and NEAR — token risk, wallet intelligence, OFAC sanctions, prices, NFTs, NEAR token and account checks, and AI-written verdicts. Paid per request in USDC over x402, no API keys.
