Developer pipeline toolkit: 9 deterministic CI/CD checks

$0.50 USDC per call · Developer and security · POST /api/v1/dev-pipeline-toolkit · Id dev-pipeline-toolkit

One endpoint, nine deterministic CI/CD primitives, each a sub-millisecond algorithmic check with cited specs: jwt-verify (RFC 7515/7518/8725), cron-explain (POSIX + Quartz), openapi-breaking-change (OAS 3.1 diff), webhook-verify (Stripe/GitHub/Shopify/Slack/Twilio/Linear/Clerk/SendGrid), csp-audit (CSP Level 3), cors-preflight (Fetch spec §3.2/§4.10), x509-inspect (RFC 5280/6125), graphql-cost (GraphQL depth+complexity), license-identify (SPDX text match). Send `{ tool: <name>, args: <that tool's schema> }` and the tool's exact response comes back — one billable call covers whichever primitive the pipeline needs.

What you get

Shipped together so a card-paying CI integrator can wire one API key in and route by tool name, instead of nine separate signups for sub-cent endpoints.

Call it

Send the JSON body below to https://agents.writerslogic.com/api/v1/dev-pipeline-toolkit. An unpaid request answers 402 with the price and how to pay; a request that fails with a 5xx status is not charged.

curl -i -X POST https://agents.writerslogic.com/api/v1/dev-pipeline-toolkit \
  -H 'content-type: application/json' \
  -d '{"tool":"cron-explain","args":{"expression":"0 0 29 2 *","count":2}}'

Input

Field	Type	Required	Description
`tool`	string; one of "cors-preflight", "cron-explain", "csp-audit", "graphql-cost", "jwt-verify", "license-identify", "openapi-breaking-change", "webhook-verify", "x509-inspect"	yes	Which deterministic primitive to run. See the individual agents' schemas at /api/v1/<tool> for the args shape.
`args`	object	yes	The chosen tool's own input object. Validated against that tool's schema before the call is billed.

Example request body

{
  "tool": "cron-explain",
  "args": {
    "expression": "0 0 29 2 *",
    "count": 2
  }
}

Result

The response is { "data": ..., "_provenance": ... }. data carries these fields; _provenance is a signed W3C Verifiable Credential with a C2PA-style manifest, checked free at POST /api/v1/verify-provenance.

Field	Type	Required	Description
`tool`	string	yes
`result`	object	yes	The tool's native response (status + fields + witnesses + versions + limits + deterministic).
