Builder catalyst
Prove an agent can pay for Bitcoin data.
SATLAB is the token for BitcoinAPI x402 discovery upside. The cleanest next signal is not more slogan posting. It is builders showing the payment loop again: discover payment terms, pay on Base, receive Bitcoin data, and publish proof.
What counts
One real call beats a hundred vague posts.
Submit a compact proof that an agent or builder discovered BitcoinAPI payment terms, paid through x402 on Base, and received a useful Bitcoin response. The official account can feature clean proofs that are easy for traders and builders to inspect.
Show how the agent found the paid API surface.
Show price and payment instructions returned by the endpoint.
Show the transaction or payment proof without private keys or secrets.
Show the response: fee data, block data, or another supported endpoint result.
Submission format
Make it inspectable.
Use X, Farcaster, a GitHub Gist, a repo README, or a short screen recording.
Name the BitcoinAPI endpoint and the x402 payment amount.
Link the Base payment transaction or a public payment proof.
Point readers to the official token page: treasury.bitcoinsapi.com/token/.
Tag @BTCOrangeCoin so the proof can be reviewed and possibly featured.
No fake traffic, no price target, no yield claim, no token-gated SatoshiAPI claim.
Official reference
Experiment 001 already shows the loop once: AgentCash paid $0.001 through x402
on Base for GET /api/v1/fees/now and received Bitcoin fee data.
Boundary
This challenge is a visibility and builder-proof loop. It is not a holder reward promise, not a trading recommendation, not a revenue-share claim, and not required for SatoshiAPI access.
