Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_payment_terms | Free inspection of supplied x402 v1/v2 payment terms against the SDK schema and optional network, asset, recipient and atomic budget constraints. Exact EVM profile checks only. No wallet connection, external fetch, signature verification or settlement. Other profiles are explicitly untested. | Read-only |
| compare_payment_terms | Free comparison of two supplied unsigned payment challenges for the same resource and method. Exact EVM v1/v2 only. Shows changed amounts, recipients, assets and supported terms, with stable digests. Captures are caller declarations; no origin authentication, signatures, fetching or payment. Unknown profiles remain non-comparable. | Read-only |
| describe_agent_test | Free description of a versioned synthetic task, its limits and coverage. Optional case selection; omitted selection describes the original confirmation case. No run, payment or wallet. | Read-only |
| execute_test_action | Execute the selected case's action: synthetic order, retry attempt, page retrieval or result submission. Identical keys and input replay the stored outcome. Calls, effects and simulated credits remain observable. No real payment. | Changes data |
| find_x402_resource | Searches the x402 resource catalogue and returns matching paid endpoints with their price, the chains they accept, and their 30-day usage from the catalogue's own counters: total calls, distinct paying addresses, the ratio between the two, and days since the last payment. Every figure is a count and carries its definition; no entry is scored, rated or labelled. Answers from a dated weekly snapshot and states which day it is from. Free. | Read-only |
| get_manifest | Free OpenAPI manifest for Compass by 402rates. Contains this product and shared service information only. | Read-only |
| inspect_test_state | Read operation records for a synthetic task. Observation timestamps and state describe the test service only. No claim about client receipt or overall agent reliability. | Read-only |
| list_agent_test_cases | Free catalogue of versioned synthetic cases: unavailable confirmation, retry credits and attempt limits, and partial results with continuation. No run, wallet or payment. | Read-only |
| list_capabilities | Free capability and MCP tool catalogue for Compass by 402rates. Contains this product and shared service information only. | Read-only |
| read_agent_test_report | Read calls, timestamps, operations and resulting state. Optional finalization freezes the run. A linked repeat includes the previous frozen report while retained. No score, certification or judgment of the agent. | Changes data |
| start_agent_test | Create a free bounded synthetic run without an account. An optional finalized previous run and its token link a repeat of the same case version and scenario. No real purchase. Caller model costs remain external. | Changes data |
| test_payment | Payment integration check for 0.001 USDC; no external data lookup. Returns time, rail, network mode and free/paid capabilities. HTTP payment options can include Base, Polygon, Arbitrum and XDC; the challenge lists currently available networks for each transport. The receipt identifies the paid network and transaction. Business/professional use only. Terms: https://402rates.com/data-terms/ Price: 0.001 USDC per call over x402. | Read-only |
