x402trustlayer.xyz

TrustLayer serves as a pre-execution and governance layer for agents that consume x402-gated APIs. It is designed for multi-agent pipelines where spending policy enforcement, endpoint reliability, attestation trust, and budget allocation must be resolved before any paid call is made. The host is distinct in combining spend governance, fleet budget distribution, attestation verification, and endpoint quality probing into a single addressable service, rather than offering financial data or transaction execution.

Capabilities

Attestation Trust

Provides the ability to query the attestation registry for known valid agents and to verify individual attestation proofs by ID, enabling agents to enforce trust requirements before acting on attested claims or admitting partners into a network.

fetch-attestation-registryverify-attestation-signature

Spend Governance

Enforces per-agent spending policy by checking proposed costs against daily and per-call USDC caps and allowed-host lists, and estimates whether an MPP session or per-call settlement is more cost-effective for a given call volume.

Fleet Budget Allocation

Distributes a shared USDC pool across a fleet of agents in a single call, respecting each agent's priority, requested amount, and daily cap, and returns per-agent approval decisions.

Endpoint Discovery and Routing

Routes natural-language capability queries to the best-matching x402 API endpoint with network and price filters, and recommends the next logical paid API step after a completed settlement to reduce agent search overhead.

Endpoint Health Probing

Batch-probes up to 10 x402 endpoints in a single call to verify they return correct HTTP 402 responses, computes per-URL health scores, and produces an overall pass/fail summary for pipeline readiness checks.

Workflows

Pre-Call Trust and Spend Gate

Use when an agent needs to verify a counterpart agent's attestation and confirm its own spend policy is satisfied before making a paid x402 API call.

1
fetch-attestation-registryQuery the attestation registry to confirm the target agent or partner holds a valid attestation at the required grade.
2
verify-attestation-signatureVerify the specific attestation ID returned from the registry to confirm it is valid and recognized by TrustLayer.
3
check-spend-governorCheck that the estimated cost of the intended paid call falls within the agent's daily cap, per-call cap, and allowed-host policy before proceeding.

Endpoint Discovery with Health Validation

Use when an agent needs to discover the best x402 endpoint for a capability and confirm it is healthy before committing to use it in a pipeline.

1
route-x402-capability-queryRoute a natural-language capability query to identify the best-matching x402 endpoint and ranked alternatives within network and price constraints.
2
probe-x402-endpoint-qualityProbe the selected endpoint (and any alternatives) to verify they return correct HTTP 402 responses and meet health score thresholds before use.

Fleet Budget Distribution with Spend Check

Use when an agent orchestrating a fleet needs to allocate a shared USDC pool and then verify each individual agent's spend policy before dispatching work.

1
allocate-fleet-budgetDistribute the shared USDC pool across fleet agents, producing per-agent allocation decisions with approval status.
2
check-spend-governorFor each approved agent, confirm the allocated amount satisfies that agent's per-call and daily cap policy before authorizing the paid call.

Payment Strategy and Post-Settlement Routing

Use when an agent needs to decide between MPP session and per-call payment before a batch of calls, then determine the next optimal endpoint after each settlement completes.

1
estimate-mpp-session-planEstimate whether opening an MPP session or paying per-call is more cost-effective given the expected call volume and average price.
2
check-spend-governorConfirm the chosen payment strategy's estimated cost falls within the agent's configured spending policy.
3
fetch-settlement-graph-nextAfter each settlement completes, retrieve the recommended next paid API endpoint to invoke based on the prior endpoint path and topic.

Own x402trustlayer.xyz? List it with your agent

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.

38 of 69 routes have never been scored — the audition tests them for the first time.
2 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
3 routes are in the 50–74 band — working, but with room to climb.
7 routes are flagged by the verifier as failing or inconclusive.

Paste this to your agent

Make my x402 API at https://x402trustlayer.xyz discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://x402trustlayer.xyz --json`. Heads up: 38 routes have never been scored and 2 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
