Results are kept 24 hours, and each can be transferred three times in total, including the original response. While the operation is pending the answer is 202 with Retry-After 5; after expiry it is 410.

Sign up at https://app.lumeus.dev: Free, Starter, Growth and Scale plans are self-serve, Enterprise by agreement. - **Pricing.** Testnet is free: Testnet requests cost no credits and are never billed. Each organization can make 10,000 Testnet requests a day across Activity, Assets and RPC (unlimited on Enterprise); the count resets at 00:00 UTC, and a request over it answers 429 rate_limited with Retry-After set to the seconds until then. Mainnet requests draw from the plan's monthly credits. Plans, limits and credit weights: `GET https://api.lumeus.dev/v1/plans`. - **Authentication.** Send `Authorization: Bearer `. Testnet: `lum_test_…`; Mainnet: `lum_live_…`. A key works only on its own network, so pick the server that matches it (the other network answers 401). Publishable `lum_pub_…` keys call the GET data routes only, from an allowed browser origin. Webhook keys (`whk_…`) are not accepted here. - **Headers.** Every response except `GET /readyz` carries X-Request-Id; authenticated responses carry RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset; 429 and 503 carry Retry-After. - **Errors.** JSON with a machine-readable code (see [errors](/guides/errors)). A path with an empty, `.` or `..` segment answers 400 invalid_request, a trailing slash answers 404 not_found, and a method the path does not accept answers 405 with an Allow header. - **CORS.** Browser calls (CORS) are allowed from https://docs.lumeus.dev (the Try it playground of this reference) and https://app.lumeus.dev only, without cookies; responses expose ETag, Link, Location, Retry-After, X-Request-Id, X-Lumeus-Operation-Id, X-Lumeus-Idempotency and RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset (errors included). Other websites cannot read responses made with a server key: use a publishable key with your own allowed origins ([browser keys](/guides/browser-keys)). license: name: Lumeus API contract servers: - url: https://api-testnet.lumeus.dev description: Testnet (default) - url: https://api.lumeus.dev description: Mainnet security: - Bearer: [] tags: - name: Queries description: >- Decoded Stellar history: the token movements and contract events of an account, asset, contract or transaction, the network feed, contract-event topic search and transaction headers. - name: Results description: >- Recover the saved result of a long prepaid request without running it again.
