How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

Output

Returns a JSON object with an 'ok' boolean indicating whether the catalog successfully registered the service, recomputed and matched the canonical SHA-256 digest, and recorded the network-effect edges.

Example use cases

Onboard new paid API to catalog

“I've just launched my x402 service at https://api.myproject.io/v1/score — can you register it in the Synthex Forge verify-catalog using this signed claim object and my Ed25519 signature, and set the service name to 'MyProject Score API'?”

Re-verify artifact after claim update

“My service claim has changed — please re-submit it to the x402 verify-catalog register endpoint with the updated signed claim and my SHA-256 hex digest so the catalog can confirm the canonical digest still matches my signature.”

Catalog service with network-effect edges

“Register my x402 endpoint https://forge.partner.io/v1/attest in the verify-catalog with my Ed25519 signature, and include edges pointing to these three related catalog services so the network-effect graph gets updated too.”

When to prefer

Choose this endpoint when you need to formally register and cryptographically attest an x402-compatible service into the Synthex Forge verify-catalog, especially when you want the catalog to independently recompute and verify the canonical SHA-256 of your signed claim. Prefer this over generic metadata registries when you need Ed25519 signature validation and network-effect edge linking as part of a governed x402 discovery ecosystem.

Side effects

Malformed Ed25519 signature returns a failure or ok:false response
SHA-256 mismatch between producer-supplied digest and recomputed canonical digest causes rejection
Non-absolute or invalid service_url causes request failure
Payment not provided or insufficient USDC triggers HTTP 402 payment-required response
Malformed edge objects in the edges array may be silently ignored or cause validation errors

Input

Schema · Request body

Field	Type	Description
claim	—	The signed output / claim to re-check (catalog recomputes its canonical SHA-256).
edges	array	Network-effect edges: other catalog entries referencing this service: [{url, name?, claimSha256?}].
signature	string	Producer Ed25519 hex signature; counted honestly as signed only if well-formed.
service_url	string	The x402 service URL being cataloged + re-checked (must be an absolute http(s) URL).
claim_sha256	string	Optional producer-supplied 64-char hex SHA-256 of the claim; catalog verifies it matches the recomputed canonical digest.
service_name	string	Optional human name for the cataloged service.
