Prices for the Startup plan are public. Errors return only a `message` string, token scopes are set through support, and the status feed lists 13 incidents since 22 July 2026.\n\n**Paid.** Paid suits a builder who wants usage metering, credits and invoicing behind one API, with restricted and customer-bound keys, OAuth on the MCP server and a free plan that needs no card. No status page, SLA figure, API changelog or rate-limit numbers were found, both advertised OpenAPI links returned 404, and card payments need the builder's own Stripe account.\n\n## Before you call either\n\n### Metronome\n\n1. Send an `Idempotency-Key` header on every POST and reuse it on retry. A cached error is returned for the same key, so use a new key after fixing the cause\n2. Give each usage event a stable `transaction_id`. Metronome ignores repeats for 34 days and accepts at most 100 events per `/v1/ingest` call\n3. On 429 read `X-Metronome-Rate-Limit-Type` (`client` or `customer`) and back off. Unlisted endpoints default to 8 requests a second\n4. With an agentic token, expect `403 AgenticMutationBlocked` on writes. Post the original method, path and body to `/v1/approval_requests` and show the person the `approval_url`\n5. Use a sandbox token for testing. The token alone decides whether a call reaches sandbox or production data\n\n### Paid\n\n1. Call `https://api.agentpaid.io/api/v2` with `Authorization: Bearer \u003ckey\u003e`. A person creates the first key at app.paid.ai. No programmatic signup was found\n2. Give every signal a stable `idempotencyKey` and resend the same key on retry. Signals without one are not deduplicated\n3. Send at most 500 signals a request. A 429 rejects the whole batch, so wait for `Retry-After` and resend it all\n4. Read the `code` field on a 429. `CONCURRENCY_LIMIT_EXCEEDED` carries no `Retry-After` and clears when an analytics query finishes\n5. Install the Python SDK as `paid-python`, the name in its README and `pyproject.toml`. The quickstart's `pip install paid` names a package we could not check\n\n## Questions\n\n### Which is better for AI agents, Metronome or Paid?\n\nMetronome scores 69.7 (B) on agent readiness against Paid's 55.1 (C), and leads in every scored category.\n\n### Do Metronome and Paid need an API key?\n\nMetronome needs an API key. Paid takes an API key or an OAuth sign-in.\n\n### Can an agent call Metronome and Paid without installing anything?\n\nYes. Metronome has a hosted endpoint at https://api.metronome.com and Paid at https://api.agentpaid.io/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/metronome-vs-paid.json, and with the fewest tokens: https://www.anchorterminal.com/compare/metronome-vs-paid.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"metronome\", \"b\": \"paid\"}`.
